How do I recognize a wear out? Does the receiver send an error message every time I try to change the NVRAM or do I have to ask it?

Thanks Ulrich, Much Appreciated, prefer to use your software. Thanks Again, mark -----Original Message----- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of Ulrich Bangert Sent: Tuesday, 23 April 2013 5:36 PM To: Time nuts Subject: [time-nuts] Z38XX Gentlemen, due to the discussion that evolved concerning Z38XX i looked up the sources and found that indeed every time the current time is read using a :PTIM:TCOD? a :PTIM:TCOD:FORM F2 is sent in advance to make the receiver answer in the format that Z38XX needs. I have not been aware that this could lead to NVRAM wear out but have been thinking this simply sets the format of the next output. I have changed the software so that the FORM F2 command is now only written once after program start. The software can be downloaded from the usual place but I have currently no time to test it. My own experiences with NV memory that can only be written for a limited number of times (EEPROM on ATMEL processors) indicates that a clever made NV writing routine would first compare the NV contents to what shall be written on a byte by byte base and write only changed bytes.
